# Question: Why magnetic lines of force are endless?

Contents

The magnetic field lines are closed curved. The conventions of magnetic field lines are emerge from North pole and merge at the South pole and inside the magnet its direction is from South pole to the North pole. Hence, they form a closed continuous loop. This is why the magnetic lines of force are endless.

## Do the magnetic lines of force ever end or are they continuous?

Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

## Why are magnetic lines of force closed?

Magnetic lines form continuous closed loops because magnetic monopole does not exist in nature. We always find magnetic poles – North and South pole which are coupled together in such a way that field lines originating from one pole ends at the another loop, forming a closed loop.

## What are the 4 basic properties of the magnetic lines of force?

The magnetic lines of force has the following properties:

• Each line is a closed and continuous curve.
• They originate from the north pole and terminate at the south pole.
• They will never intersect each other.
• They are crowded near the poles where the magnetic field is strong.

## What are the magnetic lines of forces?

Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet. The properties of magnetic lines of force are as follows. Magnetic field lines emerge from the north pole and merge at the south pole.

## Why can’t two magnetic field lines cross each other?

Two magnetic field lines do not intersect each other because if there was point of intersection, The compass needle would point towards 2 directions. Which means that the magnetic field has two different directions, which is not possible.4 мая 2020 г.

## Why are magnetic field lines curved?

Magnetic field lines curve because magnetic fields have finite curl and zero divergence. To visualize what those terms mean, imagine you have a pool of water which is moving around in some way. At each point of space in the pool, the water current has a direction and rate of flow.

## What happens when a magnetic needle is kept in a uniform magnetic field?

A magnetised needle in a uniform magnetic field experiences a torque but no net force because the forces experienced by it are equal in magnitude, opposite in direction and have different lines of action. Therefore, the net force is zero. … Due to the bar-magnet the iron nail experiences a non-uniform magnetic field.

## What are the properties of line of force?

What are electric lines of force? State the properties of lines of force.

• The field lines never intersect each other.
• The field lines are perpendicular to the surface of the charge.
• The magnitude of charge and the number of field lines, both are proportional to each other.
• The start point of the field lines is at the positive charge and end at the negative charge.

## What is right hand rule 10th thumb?

If a current carrying conductor is imagined to be held in right hand such that thumb points in direction of current,then curled fingers of hand indicate the direction of magnetic field. If current flows in upward direction then direction will be anticlockwise.

## What is Fleming’s left hand rule Class 10?

Fleming’s left-hand rule states that “When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and to the direction of the current flow.” It was invented by John Ambrose Fleming.

## Are magnetic lines of force endless?

The magnetic field lines are closed curved. The conventions of magnetic field lines are emerge from North pole and merge at the South pole and inside the magnet its direction is from South pole to the North pole. Hence, they form a closed continuous loop. This is why the magnetic lines of force are endless.

## Are magnetic lines of force real?

To describe the phenomena related to magnets, lines are used to depict the force existing in the area surrounding the magnet. These lines are called the magnetic lines of force. These lines do not exist actually, but are imaginary lines that are used to illustrate and describe the pattern of the magnetic field.

## Can you see magnetic lines of force?

Since the earth is a huge magnet with a magnetic north and south pole, the lines of magnetic force around the earth look like there is a huge vertical bar magnet running through the center of the earth. We will see in the next experiment how the magnetic lines of flux around a magnet can be seen.
